TYPEWRITING MACHINE.

Application filed September 3, 1926.

This invention relates to means for facilitating the handling of work-sheets .in typewriting machines.

The problem which is solved by means of this invention is that of copying in a condensed form on a record-sheet only the first line typed upon a statement-sheet upon which other lines of typing are also written.

A concrete example of such a problem is illustrated where it is desired to send out a statement to each one of a list of patrons, said statement having both a typed line of lirnmcial statement and the name and address of the patron as well, and a condensed record desired of the financial statement line without sinuiltaneous record of the name and address being made. The advantage gained by the present solution of this problem is that the act of typing the statements-zheet also makes the otiice record, so that the same is done without separately filling out an address and statement-sheet there after, and, in addition, errors are also imn1edialely subject to rectification, as it is at once seen from, the record what figures appeared on any statement sent out.

A. two-ply record-shei-it with carbons is inserted at therear of the platen and set to the printing line. The record-sheets are laterally msitioned by iii-ans of a front table upon whichv a series of movable shields. Said shields are interleaved between the record-sheets and carbons and are normally held in i'nt-rlfective position so that the lower edges thereof are above the printing line, thus permitting typing upon all the recordsheets.

The record-sheets are held in place by means of two front feed-rolls bearing on the projecting side edges thereof. while the regular feed-rolls are released for the purpose of permitting front insertion of a narrow state]nent-shect. The latter is positioned for the first line of typing by the'aid of the usual. wing scales. and then the feed-rolls are restored and the first line of typing is copied on the .record-sheets. Then the shields are. lowered to cover the printing line and prevent further typing 011 the record-sheets. Several other lines of typing are then writ- Serial No. 133,343.

ton on the statementsheet, which do not appear on the record-sheets.

In order that the first line of typing on the next statementsheet may appear on the record-sheet in a condensed manner near the other line of typing, there provided mechanism mounted at the end of the platen for the purpose of retracting the recordshcet to a position for receiving the second line of typing thereon. It will be understood that according to this invention the recordsheet and the state1nent-sheet are first simultaneously line-spaced a nedeteriliined number of line-spaces, and that the record-sheet is then retracted the same number of linespaces except one.

One of the features of this invention relates to means for positively holding the shields in their ineffective position. To this end there are provided a pair of clamps which. engage the under side of in-ejecting finger-pieces forming an integral part of the shields. All the shields are operated simultaneously and are tenmor'arily held in place by means of flat springs during the .icration of the clamps.

Other features and advantages will. hereinafter appear.

Figure 7 is a diagramnmtic view showing the relative positions of the work-sheets after retracting the platen and prior to removing the typed statement-form from the machine.

Figure 8 shows one of the forms which may be used in connection with this invention.

This invention is especially adapted for filling in, in a typewriting machine, a statement-form such as illustrated in Figure 8 and generally indicated by the numeral 10, and for obtaining a condensed copy of some of the data appearing thereon on a plurality of record-sheets 11.

It is desired to first type upon the term a line of data 12, which is to be copied upon the "record-sheets by means of intervening carbons 13, and. then several other lines of data which 'do'not' appear on the record sheets. The second line of data 14 indicates, in this instance, the location of 'the mortgaged property, while the last three lines of typing repi'esent the n'ame'and mailing address,'and are typed in a space 15 visible through a transparent window when the form is placed in an envelope.

The record-sheets are interleaved with the carbons andthe pack is inserted at the rear of'a platen 16 and held against displacement by means feed-rolls 17 engagingthe edges thereof. During typing the record-sheets are fed around the platen by means of feedr'olls 18, but these are released to permit the front insertion of the statement-sheet or form 10, which is positioned by means of winged scales, 19. p

In order that only a portion of the typing appearing upon 'the form 10 may be copied upon the record-sheets, there are provided a.

plurality of non-print'sliields 2O slid'ably mounted on a front table 44. The shields are designed to be interleaved between each carbon and its associated record-sheet to thereby prevent typing upon the recordsheet. Normally, however, the shields are held in their ineffective positions, as shown in Figure 1, so'that the bottom edges thereof are above the printing line The shields are held in their ineffective positions by means of clamps 21 which engage the under side of linger-pieces 22 forming 'an'integral part, of

the shields. iVhile thus holding the shields the teed-rolls 18 are ast onand the first line of typing 12 is writtin uponall' the work sheets .by means of type-bars and the carbons 13. The platen is the line-spaced and the carriage is'returned by means of a line-- spacing lever, not sholwn, but operatively connected to a ratchet 24 carried by a shaft 25 upon which the platen is mounted. This line-spacing and carriage-return movement is effective to position the work-sheets for the second line of typing 14 as indicated in Figure 4. v v

At this time the shields 20 are lowered to the posit-ion shown in Figure 4 so that the lower edge thereof is below the last line to be typed upon the form. The second line of typing may thenbe typed and the platen line-spaced in the regular manner to posit ion the same for other lilies of typing. It will be noted that these lines oi typing are not copied upon the rtaaird-shccts becau e the shields have been lOWOlTtl to cover the print ing line. During the linc-spacing movement of the platen the shields are carried along with the work-sheets, as shown in Figures 23 to 6, inclusive. After typing the last line upon the st atement-torm, the ca rriagc is returned to its normal position and the platen is automatically line-spacial. The slai'cmenl is then withdrawn and the shields are elevated to their ineilective or non-shielding posit-ion. The shields are raised by gripping the finger-pieces 22 and are pushed under springs 26 and against steps 27. The springs hold the shields temporarily while, the. clamps 21 are swung to their ell'eclive position, asshown in Figure 3, by means of a. finger-piece 28 fast to a cross-shaft 25) upon which the clamps 21 a re secured by means of screws 30. The shaft is journaled in brackets 31, which are secured to end plates 32 by means of screws 33.

Upon occasion it may be desired to hold the shields in el'l'ective lowered position, as. for example, when the work-sheets are much longer than the shields. The latter might then be line-spaced upward to inell'ective position if considerable typing were done, and the typing would then ap zar on the record-sheets, although not desired. In such a case it is but'necessary to swing the clamps 21 forward to cll'ective, obstructive or clamping position when the shields have been lowered to their eilect'ive position, in order to retain the shields in said lowered position and prevent them from being linespaced with the work-sheets, or manually raised, until the clamps have been released. According to some of the features of this invention, it is not only desired to copy the first line of typing on each form upon the record-sheets, but to copy the lines in a colldensed form so as to crowd. as many lines as possible upon each record-sheet. To this end, it has been found desirable to retract the platen to a position corresponding to the next line of typing on the 10('01(l. ll00i. since the latter have been line-spaced along with the statement-form when typing thereon. The retracting movement of: the platen is quickly accomplished by operating a handle 34 mounted on the platen-shalt-25. \Vhen the first line is typed the handle is positioned against a stop-pin 35, and since the handle is operatively connected to a ratchct-wheel 36, carried by the shat t 25, by means of a pawl 37 held in engagement therewith by a cam-ring 38, the handle will Ill loo

lill) move along with the platen when the same linespaced. The successive line-spacing positions of the platen and corresponding positions of the handle are illustrated in liigures to 7, inclusive. It will be noted that while the platen is line-spaeed seven spaces it is desired to retract the platen only six spaces so as to bring the record-sheet in a position to receive a second line of typing one line-space below the first. This differential movement of the platen is automaticilly obtained when the handle 34 reaches the position shown in Figure 4, at which time the pawl 3'? is thrown out of engagement with the wheel 86 by the action of a spring 39 which forces the back of the pawl into a groove ll) in the inner face of the (arm-ring 38. Since this disengagement of the pawl and. wheel occurs when typing the line previous tothe last line indicated by the nimieral 41, a subsequent line-spacing movement of the platen is effective to move the ratchet one tooth ahead of the pawl, so that when the handle is swung to retract the record-sheets, the pawl has escaped one tooth and the platen is rotated backwardly one space less than it was fed in line-spaee direction.

In order that the clamps 21. .may be held in either elleetive or inetleetive position, there is provided a spring 1-2 fast to the linger-piece 28 which engages notches a?) cut in one of the brackets 31. The ellfertive and, .inelli'eetive positions of the clamps are respectfully indicated in l igures 3 and 4;.

The front table 4.4 adjustably mounted on a cross-bar 4-5 carried by the brackets 3.1.. The extreme uppermost and lowermost positions of the shields 20 are limited. by upper tabs or stops 2? and by the .loW- stops 4-6 which in terpose the linger-pieces 22.

tlinee the table is adjm-etable to tltt'tllillllU- date rrcord-slieets of different widths, it has been found advisable to mount the :front feedrolls 1'? so as to permit adjustment thereof. llo this end, each feed-roll is carried by a dollecl;orspring .7 which is fast to a bracket l-Sl slidably mounted on a cr0ss-shaft 48.

Sometimes it may be desired to obtain a copy in full. of the statement-slieet. In. ordrr to facilitate lnrndling of this copy sheet it is proposed. to provide a, backing 50 which attached to the original statement-sheet by a weakened line of perforations. A carbonsheet 5.1 is inserted between the sheets and the pack is then front inserted, bottom edge first.

Variations may be resorted to within the scope of the invention, and portions of the improvenients may be used without others.
